When was the last time a song made you want to pee? Well, there is a first time for everything, and your first bladder-rocking beat may come courtesy of the Spica water speaker.

As Unplgged noted, it's kind of like "an audio version of a lava lamp," which seems like a good way to describe a speaker that utilizes light and water. It's only a concept at the moment, but I like the visual approach to music. [Yuki Yamamoto via Designboom via MocoLoco via Unplgged]
